how do you integrate cos2x cosx? - The Student Room有網友提問:哆啦A夢為什麼要住在壁櫥裡?嗯,關於這個問題,在網路搜到比較精細的回答如下:大雄臥室對面的房間存在嗎?在不同的情況下,大雄家裡的設定是不一樣的(後面細說)。這個房間有時存在,有時不存在。當存在時,這個房間被有的網友認為曾是奶奶的房間。但是筆者目前沒找到確切的證據,姑且稱之為「神秘房間」吧cos(2x+x)=cos2x cosx - sin2x sinx cos(2x-x)=cos2x cos x + sin2x sin x so you have two equations cos3x and cos x. Add them together you get 2cos2xcosx = cos3x + cosx divide both sides by two 1/2 (cos3x + cosx) then integrate...
